register helper functions that can be used with LESS, the same way that handlebars helpers are used in templates.

Usage

HEADS UP! This currently is not an npm module!!!! I need to come up with a different name, this is a placeholder!!!

var less = require('less');
var register = require('less-css-helpers')(less);

Registering helpers

Register a single helper

Example assets helper, that might be used for dynamically calculating the path to a project's assets directory, relative to the css file's destination.

register.helper('assets', function (path) {
  return 'dist/' + path.value + '/assets/css';
});

Register multiple helpers

register.helpers({
  assets: function (path) {
    return 'dist/' + path.value + '/assets/css';
  },
  foo: function () {},
  bar: function () {}
});

Using helpers

Example of how to use the assets helper we just created above:

@theme: "blah";
@assets: assets("@{theme}");

.image {
  background: url("@{assets}/bar.png");
}

Results in:

.image {
  background: url("dist/blah/assets/css/bar.png");
}

Properties

The following properties are exposed on the this object:

• options: Any options passed to render are exposed on this object
• less: the less object

Example

register.helper('assets', function (path) {
  return path.join(path.value, this.options.assets);
});
